In Germany December 19, 1929 4 Claims. (01. 80-19) This invention relates to a device for rolling sections having relatively high transverse ribs or an irregular profile which comprises a roller and a rolling table which passes under said roller and s is providedwith recesses producing the irregular profile. In rolling such sections there is the disadvantage that ,the surfaces of the longitudinal side-edges oi. the ribs are not smooth and solid, more especially when the profile oi the projections of the base section is of larger shape. The cause of this phenomenon has not been yet satisfactorily explained but it is surmised that it is connected with shrinking or is due to the fact that the enclosed air cannot completely escape. r

The object of the present invention is to remove this objection.

- According to theinvention the said recesses ofthe rolling table are machined along their longitudinal lateral surfaces more and in another form than corresponds to the final shape and dimensions' required. For this purpose the said recesses are provided with pyramidal 0r wedge-shaped raised parts, the apex and edge of which face the operating roller. The machining of the recesses may in each case extend to a part of the adjoining lateral edges of the base section. Where it is undesirable to have raised portions in the completed section they may bemachined down. This constructionhas the advantage that very sharp edges are produced by the increased pressure that is produced by the said wedge-shaped or pyramidal raised parts. \v g The invention is diagrammatically illustrated by way of example'in the accompanying draw- .ings, in which:-'- 4 Fig. 1 is a cross sectional view through one of the completed bars showing in elevation a rib thereon.

. Referring ngmmore particularly to the accompanying drawings. there is provided a profile bar 1 with a transverse rib 2 v formed integral therewith. Prior to being completed as shown in Figs. 1 and 2 the bar is arranged in a fitting 3 having atransverse recess 4 at the bottom thereof in which the'material is rolled so as to provide the rib or projection 2. The fitting is mounted in a rolling table indicated iragmentarily at .4, said table cooperating with the roller 5 (Figs. 3 and 4) substantially in accordance with the apparatus shown in my copending applications 455,835 filed May 26, 1930 and 506,965 filed January 6, 1931. The formation of the base of the fitting 3 is denoted by 7. p

As shown in Figure 7 the fitting 3 is provided with a wedge-shaped raised part 6. This part produces an increased pressure on the surfaces of the longitudinal sides by its wedge-shaped formation, so that they are formed solid at the edges. Where the raised parts formed by this formation of the fitting 3 in the completed profile are unquently machined down without difliculty.

In Figure 8 in addition to the wedge-shaped raised portions the lateral edges. of the fitting are machined down further than corresponds to the flnaidimensions required for the section bar whereby a satisfactory edge to the longitudinal lateral surfaces is obtained. 4

Figure 10 shows a further machining of the lateral surfaces up to a part of the base section,

for the lateral surfaces.

"The dot and dash lines show in each case the boundary lines of the finished section bar after the superfluous parts (see Figures 7 and 8) have been machined down. $5
